Dear de Brere,

Deglaciation events are primarily precipitated by the reducing elliptical eccentricity of the earth’s orbit as it oscillates from an elliptical to a circular orbit. This means that the initial T rise associated with deglaciation is not caused by rising CO2 levels. This does not disprove the link between CO2 and T.

However, your approach concerning the vibrational modes of GHGs such as CO2 is an eye opener to me! I had no idea you did not understand excited electron orbits and vibrational modes all this time. I guess this is why you don’t agree with my balloon analogy!

I can recommend some pages at Caltech and Harvard: Google: “CHAPTER 7. THE GREENHOUSE EFFECT” and click on the seas.harvard link, and Google “vibrational mode of co2 “and click on the wag.caltech link titled “IR Spectrum”.
